  • Discussion

    2. Curtia obtusifolia (Bentham) Knoblauch, Bot. Centralbl. 60: 357. 1894. Fig 74. Schuebleria obtusifolia Bentham, Hook. Jour. 6: 194. 1854. Type. Prope San Gabriel da Cachoeira, ad Rio Negro, Brasiliae, Jan-Aug 1952, Spruce 2011 (holotype K, isotype NY). Knoblauch transferred Schuebleria obtusifolia to its proper assignment in Curtia, but he left the name dangling without reference to the original publication by Bentham. The completed reference made above legitimizes the transfer.
